This is a page-flipping magazine that I inserted into a post:backticks
<iframe width="525" height="342" src="//e.issuu.com/embed.html#1065221/2182477" frameborder="0" allowfullscreen></iframe>backticks

I would like to have this as my featured image. Is that possible with your plugin? If not, is there another plugin that does this?

By the way, I used your plugin for another post that needed a video as featured image - worked fabulous - thank you!
